Facilitates designing the AC/DC power supply system for CD radio cassette recorders. A wide variety of control circuits incorporated, which realizes further miniaturization in electronic products. The adoption of a low-saturation regulator circuit reduces internal power dissipation.

featureof the LTC4053 is also implemented so that charging isinhibited if the battery is too hot or too cold.Two things must happen to add high rate adapter-basedcharging. The first is that the USB input must be isolatedfrom the adapter to prevent adapter power feeding into theUSB. The second is that the higher charging rate must beselectable by changing the resistive load on the PROG pin.A P-channel MOSFET, Q3, is used to select between USBor adapter power. Q3 is on if USB power is present and

The TK70203CS2G0 is a low dropout linear regulators with on/off control, which can supply 8mA load current.

The LP3910 is a programmable system power management unit that is optimized for HDD-based Portable Media Players.

The SAMES SA2007P is a single phase bi-directional energymetering integrated circuit. It provides a cost effective solutionfor energy meters with electro-mechanical displays, such asstepper motors and impulse counters. A precision oscillator,that replaces an external crystal is integrated on chip.Two current sensor inputs allow the measurement of energyconsumption on both the live and neutral lines.Direction detection of energy flow as well as other commontamper conditions are flagged.

The XRT72L52, Two Channel DS3/E3 Framer IC is designed to accept user data from the Terminal Equipment and insert this data into the payload bit-fields within an outbound DS3/E3 Data Stream. Further, the Framer is also designed to receive an inbound DS3/E3 Data Stream from the Remote Terminal Equipment and extract out the user data.
